The most important thing u have to know is; don't ever exchange to cz corona from streets or exchange offices with "0% commission" motto. They are everywhere and they are all deceitful. Go to Mostafa from Zakaziq. He is very kind and generous with all egyptians. His exchange office is located in wenceslas square, prague 1. Very close to Sephora, H&M and Mustik underground
Places; old town, charles bridge, prague castle, karlovy vary (not on sundays), cesky krumlov. In general wonderful place and prices are much cheaper than west europe. For shopping there are Van graf mall and paladium mall
